I hear you for sure re: closed source. I would personally really love
to see it opened up for the world to make use of too. Can't say there's
anything in the company road map and I doubt they will open up the app
code but stay tuned for news on the protocol.
We've noticed Bluetooth and WiFi interference at times (scanning for
nearby clients on BT can sometimes knock out WiFi for example) but most
chips in smartphones and laptops can use BT and WiFi simultaneously for
transmitting data. We also use WiFi direct for those Android devices
that support it. There's a reason why this sort of thing is only
possible with the emergence of smartphones. It's just too bad we can't
reach iOS users.
I just imagine an area with meshed home routers plus the overlay
meshing for a super efficient infrastructure which optimizes for energy
/ battery consumption, extending each nodes reach and offering
redundancy for backup connections. Each mesh works well on it's own but
they're also complimentary.
Thanks for the feedback! ;)
